J OINT-FASTENING FOR FURNITURE.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed December 18, 1912. Serial No. 737,378.

To all whom it may concern:

Be it known that I, ALFRED A. ANDERSON,

a citizen of the United States, residing atthe city of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Joint-Fastenings for Furniture, of which the following, taken in connection with the accompanying drawings, is a specification.

The invention relates to improvements in fastening devices for furniture and is an improvement upon my joint fastening for furniture as shown in my application for Letters Patent filed September 28, 1911, Serial No. 651,707 and the object of my present improvement is to provide a simple, strong and convenient fastening for removably fastening together two parts of a piece of furniture, which fastening is so constructed as that all the parts of the detached fastening are united as one piece, being held together by the fastening wedge; and the invention consists in the combination and arrangement of the parts as described in this specification and shown in the accompanying drawings and pointed out in the claims.

In the drawings, Figure 1 is a rear elevation of a dresser showing my joint fastening as used for attaching the mirror supporting frame to the body of the dresser; and Fig. 2 is an enlarged detail elevatlon of one of the fastenings as attached to the rear of the dresser and mirror supporting frame. Fig. 3 is a side elevation of a portion of the end of the dresser and lower end of the mirror supporting frame, showing the parts of the fastening in the adjacent position which they would assume when about to be connected; Fig. 4 is a side elevation of the wedge; and Fig. 5 is a similar view of the parts shown in Figs. 3 and 4 of the attached fastening with the wedge inserted. Fig. 6 is a perspective view of the detached upper portion of the fastening; and Fig. 7 is a similar view of the lower portion. Fig. 8 is a plan view of the underside of the assembled fastening showing the construction and assemblage of the parts. Fig. 9 is a plan of the upper end of the fastening as attached to the mirror frame, the mirror frame being shown in section.

Like numerals of reference refer to corresponding parts in the several views.

The numeral 10 designates the body of the dresser, and the numeral 11 the mirror supporting frame. It is obvious that these parts must be firmly united, yet so that the mirror frame maybe quickly and easily removed from the body of the dresser. Wooden cleats have been used for this purpose. This necessitated the insertion or drawing of the screws whenever it was desired to attach or detach the frame 11 to the dresser top. These wooden cleats were usually shipped with the dresser to be attached by the purchaser or retailer.

This joint fastening consists of the two plates 12 and 13 which have the Ushaped loops 14 struck therefrom. The plates above and below the loops 14 are oppositely extended, as shown at 15, so that when the loops 14 are struck out into position the extensions 15 come together on a central line 17, as shown in Fig. 8, thereby providing a firm sheet metal support for the inner edges of the wedge 16 when inserted beneath the loops 14. In order that the end screws may not spread the joint 17 apart a semi-circle 18 is provided in one part around the end holes 19 thereby strengthening the joint between the two parts and holding the plate firmly in line.

The extensions 15 each side of the joint 20 between the two parts 10 and 11 and 12 and 13 are formed as closely as possible to said joint and greatly strengthen both the plates and said joint. The screw holes 21 each side of the joint 20 are placed as near as they will hold in the wood. An additional pair of holes 22 may be punched in the metal plate to insure the attachment of the plate, as for example in the edges of veneer boards here the screws can not be placed as close to the edge as upon solid lumber. The loops 14 are also placed close to joint 20 and .are struck from the sheet metal plates by suitable dies, it only being necessary to make them sufliciently strong to hold the wedge 16 each side and adjacent to the joint 20.

The lower end of the upper plate 12 is turned in two right angle flanges 23 each side of the loops 14 so that the wedge 16 may pass therebetween. The upper end of plate 13 is turned in two return bend flanges 24 which receive the flanges 23 therewithin. The width and length of the flanges 23 and 24 are proportioned one to the other so that when the two plates 12 and 13 are placed with the flanges 23 within the flanges 24 and the wedge 16 is inserted through the loops 14 it will hold all the parts firmly to gether so that the assembled fastening may be placed in the drawer of the dresser the same as the wood cleats, as hereinbefore mentioned, and the fastening can be attached by the purchaser or retailer the same as said wood cleats and does not have to be attached at the factory. The complete assemblage of each individual fastening also PI'EVGIltS the loss of the parts and shows the purchaser exactly how to attach the same.

It is essential that the wedge 16 should be made with an outward bend or curve through its central portion, as shown in Figs. 4t and 5, so that said wedge draws firmly upon loops 14 each side of the joint 20 and bears on its inner side on the end portions 25 as said end portions bear upon the projections 15 of the plates 12 and 13, thereby insuring a quick and firm bearing and release, since the metal of the wedge 16 bears upon the metal plates 12 and 13. The wedge 16 is preferably struck out in the U- shaped form from a suitable piece of sheet steel and given a slight curve by means of suit-able dies.

The office of the flanges 23 and 24 is not only to form a stronger attachment between the plates 12 and 13 and the parts to which they are attached but is more to hold said plates in line with one another and with the joint 20 between the two parts to be fastened together. By being thus held in line and at a spaced distance in respect to one another the two loops 14 are so spaced that the tapered spring within said loops is proportionate to the tapered wedge 16 so that said wedge invariably fits perfectly and has a stronger hold within said tapered openings in both of the loops, also that the outwardly curved wedge 16 more quickly finds a bearing within said loops yet may be easily released therefrom by a tap of the hammer, though while in the holding position bears perfectly upon both of the parts 12 and 13. This alinement also is aided by the projecting portions 15 and 15 of the plates 12 and 13, since these projections insure a perfect metallic bearing for the portions 25 of the inner sides of the wedge 16. It is also obvions that the two plates 12 and 13 must be attached to one another, or when attached to the mirror frame and dresser the mirror frame could be lifted from the dresser by simply lifting the wedge out of the loops 14, since there would be nothing to hold the mirror frame except the wedge 16. The connections 23 and 2 1 prevent such an action.

I claim as new- 1. In a device of the type set forth, a pair of metal plates, each plate consisting of a pair of opposite side parts and a loop which is integrally connected at its ends to the confronting inner side edges of the side parts, said confronting inner side edges of the side parts being in abutting relation and alined with the loop interior and extending above and below the loop, one side part having a substantially semi-circular perforated projection extending from the inner side edge thereof and the other side part having a cut-out part on its inner side edge to receive said projection, the loops of the plates being arranged in alinement, and a wedge of substantially U-shape in cross section received in the loops and having the longitudinal free edges of its legs for direct ongagement with portions of said side parts of the respective plates that are alined with the loop interior.

2. In a device of the type set forth, a pair of metal plates, each plate consisting of a pair of opposite side parts and a loop which is integrally connected at its ends to the confronting inner edges of the side parts,

one side part of each plate having a substan tially semi-circular perforated projection extending from the inner side edge thereof and the other side part of each plate having a cut-out part on its inner side edge to receive said projection, said perforated projections and the loops of said plates being arranged in alinement, and a wedge for engagement in said loops each side of said perforated projection.

In testimony whereof I have aflixed my signature in the presence of two witnesses.
